Any Ideas On How To Remove Dust From An Image??

Update...


After further testing, it is in fact a dusty sensor. I tried with both the 24-105 and 70-200 and the particle shows up all in the same region. To make things worse, I attempted to manually clean via the blower, and now I

Short of the blower, I wouldn't recommend trying to clean your sensor with anything but a product specifically designed for sensor cleaning. Is there a major photo store anywhere near you (Henry's, Vistek)? They will likely have something to rescue you. Or, depending on when you leave tomorrow, you can possibly have something overnight shipped? I've gotten great results with theVisible Dust Arctic Butterfly 724 Super Bright..


Or, use the Dust Delete function. Or clone out the spots in post.


Good luck, and have a great trip!

Henry's has the solution that you have mentioned, so I'll check them out tomorrow as I'll be in their *neck of the woods* for some last minute shopping - the flight is @ 22:30 pm have plenty-o-time to kill.

You know it seems to create fear when you start talking about cleaning a sensor. I stuck with the blower for a long time before I finaly graduated to somthing else. Alot of people like the brushes, and I have talked to alot of people that do not. The local camera shop does not use the brush. It is my understanding if you use a brush, the idea is to generate static that attrackts dust, not sweep the sensor. Any one can correct me here if I am wrong, because I do not use the brush.


So about 6 months ago when the sensor got really dirty on the 5D II I decided it was time I took the plunge. I used these with some cleaning sensor solution:

It took me about 7 of them to get the sensor clean. You use these with a bit of sensor cleaning solution. Use them only one swipe and discard. Make sure you have the right size swab for your camera.Use a fluid motion from one side to the other firm but gently stroke. After you finish use the blower and blow it off, then check it again. Most common is it will leave a little resude in the corners. It may leave small pieces of lint that easily blows out. Put the lens on, and retest. Sometimes it takes a few trys before you finaly get it all.


That was a short explanation, there are several videos on the net that tell you how to do this. Watch a few of them, make sure you have a full battery charge, go slow and be carefull.


When I bought my 1D IV it was dirty as heck right out of the box. I had to clean it first thing, kind of disapointing that Canon wouldn't QC there top camera for cleanliness.


Don't take this as my recomenation to try or not. It is your camera and sensor, take what risk you feel acceptable with your skill level and abilities.


Good Luck

You might also consider taking a swab/q-tip and rolling it around it the bottom of the box first before using your blower. Most dust gets shook down there after every use and blowing it out first will send a plum of junk all over the place.

Manually cleaning the sensor is not to be feared. The swab method works very well. Usually, they provide a solvent (methanol) that is dropped onto the swab, just before cleaning the sensor. This will dislodge stubborn particles.


I think I remember reading that you're not actually touching the sensor, but an IR filter that covers it. Just follow the instructions on how to wipe the slightly damp swab across the sensor area.


Be sure NOT to touch the mirror with the swab.

After yesterday's results, I decided to look at some other photos taken in the past where I had the aperture dialed up high. Boy was I surprised.
Check out this ugliness of a photo rendered in HDR, can you count the number of dust spots??





Canon EOS Digital Rebel XSi, 0.004 sec (1/250), f/14.0, 10 mm, ISO 200, 2009.


And to think that all this time I thought it was all lens related - I should just return my gear and stick with a point and shot!


I may very well use my gear as is and upon my return send it out to Canon for a complete cleaning. Just need to keep that aperture wide open as possible!


Also, Adobe Lightroom does a great job of removing the specks.


Thanks for all your input!
